In October 2018, Damon Wayans announced his exit from the series, saying he would leave following the end of production for the third season in December 2018.[4] However, Fox Entertainment CEO Charlie Collier stated in February 2019 that there is a strong possibility of Wayans returning if the series were to be renewed for a fourth season.

After these statements, producers rearranged Wayans' shooting schedules and provided diabetic meals for him on-set.[28]
